What does the permanent green dot on electric outlets mean? The green dots indicate that the UPS outlets and plug are certified as hospital-grade and may be used within patient-care vicinities.
What does a blue dot on an electrical outlet mean? These indicate the need to balance the loads on the generator when adding the electrical devices. For example, if you are adding two electrical devices, plug one into a red outlet and the other into a blue outlet rather than two red or two blue outlets. This will help balance the loads on the generator.
Which synapses are quickest? Compared to chemical synapses, electrical synapses conduct nerve impulses faster, but, unlike chemical synapses, they lack gain—the signal in the postsynaptic neuron is the same or smaller than that of the originating neuron.
Why are chemical synapses slower than electrical? Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels.
